Question

Solve for x: 3|2x − 2| + 6 = 18.
x = 3, x = −3
x = 3, x = −1
x = 1, x = −1
x = −3, x = 1

Answer 1

Answer 2

Add -6 to both sides.
3(|2x−2|)+6+−6=18+−6
3(|2x−2|)=12
divide both sides by 3
we are left with this
|2x−2|=4

Answer 3

We know either 2x−2=4 or 2x−2=−4

Answer 4

2x-2=4
solve this for x

Answer 5

x=3 ?

Answer 6

Yes so one of out answer is x=3 now solve this for x
2x-2=-4

Answer 7

answer is x=3 , x=-1 ?

Answer 8

Yes :) well done

Answer 9

Thank You
